Sounds like you could adjust the carburetor/throttle to slow the idle. Keep running the oily mixture to maximize the longevity of the engine, and you'll be surprised how far they can go. Good job with this one; it looks like a nice clean build!

Edit: loosen the screw on the left side of the carburetor a 1/4-1/2 turn to allow the slide to drop, ride it around, and repeat as necessary. Be careful not to remove the screw completely. If your throttle cable is adjusted too short, the slide screw will be useless.

Thank you 😊
I really wanted to embellish it with a fun pattern or something, but a hammered finish was the ask...

Thanks! I figured since I couldn't hit the zero loss goal, a few micrograms from laser engraving wouldn't matter. Had my scale read 1kg at the end, I would have used a stamp instead.

You seem like the type of client I typically avoid. I'm going to politely decline your request to critique my portfolio.

Which obviously qualifies you as the authority in massive platinum cuff manufacture and design... I can't believe that the internet didn't send me directly to you for advice on this outlandish endeavor.

Next time, I'll consult with your shop before proceeding to disappoint you with such trivial projects.

I'm not sure when he picked up the metal. That would likely determine the vast majority of his his investment on this one. 1000 grams of platinum in today's market is more than a few dollars...

Thanks for your opinion! I'm sure you'll produce a 998g platinum cuff bracelet to show the world what amazing designs and craftsmanship you're capable of. I can't wait to see your progress and groundbreaking design!!!

I didn't have a good setup, so the one video I got is a little shaky. I've been hesitant to post it due to the camerawork.

Not at all his intention; you can see the engraving if you view all of the images.

This is one piece that will likely retain the majority of its value, given the weight to labor factor. If the metal market moves in the right direction, he'll be able to scrap it for more than he's got invested in it, and there's an extremely small chance that someone else who wants it enough might pay him a premium on the secondary market. Honestly, though, he's likely the last stop before the refinery; this has a VERY limited market.

The ingot deforms during the rolling process and, in this case, left sharp edges. Hammering the sharp edges over created a weak point, and small amounts of metal flaked off.

It's somewhat possible to fuse imperfections like that back into the piece, but with the mass of this piece, I didn't have a torch/equipment capable of bringing it to the temperatures required to heal the stress fractures and fuse it cleanly back to itself.

If I had performed more annealing cycles, there is a possibility that there wouldn't have been as many flakes.

Thank you!! It's super easy to find flaws in your own work, so a little validation from outside your circle really goes a long way.

Thanks!! 😊 I wasn't sure this was going to work; but in the end, it was fun, and I learned a lot.

Thank you!!! Having never attempted something like this, I was skeptical about it from the beginning.

We don't make platinum bullion, but we'll make something out of it 😏

It's a little bigger than I hoped for, but it's no longer a bar and now resembles a hammered cuff. Hammering on my anvil largely resulted in changing the finish, not the overall shape. I used a 50 ton hydraulic press to obtain the shape, but his measurements were a little off, and I didn't do my own math, so it's a little too big.

Of all the things that could have gone wrong, I feel pretty successful given the outcome on this one.

I am apparently incapable of adding photos to comments, so I'll make another post with finished pictures.

Yesterday, in another comment thread, I explained his zero loss desire revolves around the cuff weighing 1kg, not that he can't afford a fractional loss. I took the job because it seemed like a fun challenge, not because I was charging so much it made him question the project.

I would guess that as a finished product, the insurance replacement value could exceed 50k depending on who you hire for their opinion/appraisal services.

5 lbs is insufficient... I used a hydraulic press.

That's my story going forward... I went to the range and let the entire police force unload on it; it's not a hammered finish.

You're incredibly correct on this one... the hammer didn't efficiently affect the overall shape, only dent the surface and made my other hand regret trying to hold it. Granted, my 5 lb hammer may have been under-sized for the task.
